The decrease in the cost of crystalline silicon cells mainly depends on the increase in conversion rate, decrease in the thickness of silicon wafers, and the decline in the price of raw materials. Compared with crystalline silicon cells, the cost of thin-film solar cells has more room to fall, mainly due to the following factors: economies of scale, Increased conversion rates, lower equipment prices, and lower raw material costs.
The long-term competitiveness of solar power must be a breakthrough in cost, so what is the cost? When it can be reduced to the level of thermal power or even lower than thermal power, it is an important indicator to determine the stage of development of the industry;
In this report, I will measure the actual cost of solar power. Calculating the cost of solar power requires four sets of data: the price of components and systems, the duration of sunshine, the cost of maintenance, and the depreciation period. The first two are the most important.
According to the calculation, in the current sales price of components, the lowest domestic cost of Lhasa, the cost per kWh is 0.61~0.68 yuan/kwh. Guiyang, which has the highest power generation cost, has a power generation cost of 1.321~1.42 yuan/kwh.
According to 2100 hours in the better sunshine region of the United States, the cost of electricity is 0.12/kwh and the maintenance cost is $0.01/kwh.) The proportion of oil and gas is slightly higher; if the level of sunshine in the northern United States or Germany is low, the electricity is generated. Cost is $0.25/kwh
Judging from the future changes in the cost, there is no change in the duration of sunshine and depreciation, and the main reason for the decline in the future is the system price. According to the current situation, the module price has a large space for decline.
